Application filed Ja ne,

ToaZZ whom-2725 may concern; a

Be it known that I, ALrnnn M. DnMUrH, a citizen of the United States,.residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements inIndividual Work- I Holders for Slicing-Machines, of which the following is a specification.

.This invention is particularly adapted though not necessarily limited in I its use with slicmg machines embodying acarrlage the cutting plane, with the result that: the

first few slices that are. cut from the re-, placed article will be imperfect and broken slices and not of a uniform thickness, resulting in dissatisfactionto the customer or Itis one of the objects of the present inventionto provide an individual work holder for each of the articles to be cut and to which holder the article is fastened, so I that the article may be removed with the holder and again replaced in the machine with the holder. The article being secured tothe holder will insure the proper positioning of the article with respect to the cutter to insure a complete and perfect initial slice of a uniform thickness. At the same time, the use of such a holder will obviate the ne-, cessityof the merchants hands constantly coming into contact with the article,thereby insuring sanitary conditions.

A further object is to provide an improved individualholder ofthis character having improved means for securing, the article thereto while theholder is either or out To the attainment ofthese ends and the; accomplishment of other new and \useful objects as will appear the invention consists in the features of novelty in substanend of the clamping bar.

Fig. 5 isa perspectiveview of a slightly I modified form of the work holder removed from the machine and showing the clamping bar in position. a I I F 1g. 6 is a detail perspective-view oftone ing the numeral 10 designates the table of a slicingmachine which in the present form ofthe invention is adapted to reciprocate with respect to the cutter 11 as usual in machines of this character, I

.T he table 10 is mounted thereon and the work support. 12 which is adapted to be intermittently advanced with respect to the table 10 'at predetermined points in the relative movement of thetable ,and the cutter, as

is also common in machines of this char- I acter. I

This work support 12 is provided with the usual toothed uprights 13 and 14, and movable thereupon is the usual clamping bar 15.

The individual I. or supplemental work holder'embodies a support 1.6 which is preferably provided with upstanding edges or flanges 17 and is also preferably provided with ya series of apertures 18 opening through the :front edge thereof and a plurality of slots 19 opening through the body of the holder. f

The upper edges of the flanges 17 preferably taper toward the rearof the supple.

mental support 16 for the purpose of light ness and this supplemental support. 16 is preferably of a size substantially equal to the work support12. y

Projecting upwardly from one of the sides 16 ofthe supplemental support is an upright 20 provided with a series of angular shaped apertures or slots 21 and thls upright 20 may be formed separately from the supplemental support and secured thereto by means of suitable fastening devices 22,

,or, if desired may beformed integral there- 7 With.

Arranged on the opposite side of the holder is 'anotheriupright 23 havmg a series of slots 24: opening throughone edge there- 'of. This upright 23 is pivotally connected 'Wlllll the support 'andhas a h-andle26 by means of Which the upright may be moved about its; pivot, the direction of pivotal movement being transverse to the cutting plane. 'A; pin 27' is -preferably connected to I the upright'23 and 1s adapted to operate in aslot 28 so as-to 'limit the pivotal move ment of the upright'23. Y

" These uprights 20 and 23 arearranged' ad- 'jacent'butjare preferably spacedback of the 'front'edge of the supplemental support 16 and which' edge contains the openings 18.

' r A suitable clamping "bar 29 cooperates with the uprights 20 and 23. This clamping bar may be of anvdesired size and configurationand isprovided with teeth-30,

and-oneend 31 of the barris preferably reduced or shapedto form an'angular ex- .tremity'adapted to be inserted into and to conform with the apertures 21 in the upright-20. The otherend of the bar 29 is provided with a suitable handle 32' and is also j-providedwith a reduced portion 33 adapted to enter the slots 24 for holding the I clamping bar in position.

a f as'tojforee the teeth 30 of thebar into the *article. The upright 23 before the bar is placed in position is moved about its pivot 25'into theposition-shown in dotted linesin Fig. WVhen the: bar is placed in position as justabove described, the handle 32 is held depressed and the upright 23 is moved by 1 the handle 26 about its pivot 25 so that the reduced portion 33 of the bar will enter one of'the slots 24:. This, as will be seen, will "securely fasten the article to the supplemental support;

. Thesupplemental support with the article I thereon is-then placed in position upon the work support 12 of the machine so that the openings 18 'in the front edge of thesupplemental support will be; in positions to re- :ce ive the pins 31on the Work support 12.

The clamping bar 15 on the work support 12 is then moved downwardly upon the uprights 13-14 until it engages and clamps the article upon the work support.

When the parts are in this position the slicing machine is operated and the supplemental support will be intermittently advanced with the work support.

When it is desired to interchange the articles the clamp 15 is raised and the supplemental support with the article fastened thereupon may be removed from the work support while the rest of the machine is intact by simply raising the supplemental support from the machine by the'handles 35. When the supplemental support is in position the slots 19 will receive the pins 36 which are mounted upon the work support 12.

Vith this improved construction it will be seen that when an article is replaced in the machine together with the supplemental support the front edge, or the face from which the slices are to be cut will be arranged in a plane parallel with the cutting plane so that the first slice will be a complete unbroken slice of a uniform thickness.

.The articles being secured to the holder, can be readily placed therewith into the ice box or upon the counter thereby obviating the necessity of the merchant handling the articles when they are interchanged in the machine.

is shown in Flg. 5, the supplemental support 37 may be provided with a series of ribs or corrugations 38 extending lengthwise of the support and in a direction transverse to the line of cut. The crown of each of the corrugations is preferably flattened so as to form sharp edges 39 so that when the article is clamped upon the supplemental support the edges of'the corrugations will embed themselves in the article and will hold the article against a lateral shifting movement when the knife or cutter contacts with the article.

.While the preferred form of the invention has herein been shown and described, it is to be understood that various changes may be made in the details of construction and in the combination and arrangement of the several parts within the scope of the claims without departing from the spirit of this invention.
